Help Please - Wiring Diagram BMW E60 RDC Module
 

Help please - no one's at home over on the BMW tech side. I have a '08 528XI where the RDC module is not 'recognized' by the car's network or Autel software diagnostics.

I have replaced the Module with new, same situation. These do not need programming as it is the basic TPMS system BMW has, plug and play. It communicates through the ABS unit apparently.

Back in the winter when it was very cold, I was driving to work over some rough road, then the TPMS light came on. From that point on I started diagnosing, removed the module and checked the pins / connector for issues with contamination, broken wiring, etc. As I said above, ultimately replaced the unit and the issue remains.

I'd like to find info on pinout as there are only 3 or 4 wires connecting. Specifically where it receives power / ground. I checked the RDC fuse in the trunk, has power on both sides with key 'on'
